prenatalna

Prenatalna refers to the period of development before birth. This crucial stage begins at conception and continues until delivery. Throughout the prenatal period, a fertilized egg undergoes rapid cell division and differentiation, forming specialized tissues and organs. The developing organism, known as an embryo initially and then a fetus, relies on the maternal environment for nourishment and protection.

The prenatal period is typically divided into three main stages: the germinal stage, the embryonic stage, and the fetal stage. The germinal stage, lasting about two weeks, involves fertilization and the initial implantation of the zygote in the uterine wall. The embryonic stage, from the third to the eighth week, is characterized by the formation of major organ systems. The fetal stage, from the ninth week until birth, focuses on the growth and maturation of these organs and systems, with the developing being becoming increasingly recognizable as a human.

This period is highly sensitive to external factors. Exposure to certain substances or conditions, such as infections, radiation, or teratogenic drugs, can have significant impacts on the developing fetus, leading to congenital anomalies. Therefore, prenatal care, which includes regular medical check-ups, proper nutrition, and avoidance of harmful exposures, is vital for ensuring a healthy pregnancy and optimal fetal development. Medical professionals monitor the progress of the pregnancy, screen for potential risks, and provide guidance to expectant parents.
